MULTIPLE GLASS FEEDER.

Application lled March 31, 1921, Serial No. 457,299. 'Renewed March 11,1924.

This invention relates to a process of and apparatus for obtaininguniform gathers or charges of molten glass from a supply thereof i a Toperform this process, a plurality of puntjes or other gatheringimplements successively move into contact with a mass of molten glass,accumulate gathers therefrom, and move away to a position where the logathers may be further manipulated or presented to mechanism forsubsequent treatment. Y

In some instances, as for example, where the gathers are to be formedinto incandescent lamp bulbs, it is desirable to subject them to furthertreatment, such as marvering, to preliminarily shape them and form askin or enamel thereon, and this invention also provides means foraccomplishing this result.

It is also an object of this invention toA provide a new and improvedmeans for retaining the gathering devices removably in a carrier. Thismethod and a preferred apparatus for carrying it out are illustrated inthe accompanying drawings, although various other forms of ments fallingwithin thescope of the appended claims, might be used.

F ig. 4 is a partial horizontal section on the ine 4-4 of Fig. 2,showing the mechanism for intermittently rotating the carrier.

Fig. 5 is a detail sectional view taken on the ine 5 5 of Fig. 1,showing one of the chucks for removably holding the gatheringimplements.

In the embodiment of the invention shown herein, the glass deliveringmeans, comprises a suitable furnace 1 provided with an orifice 2,preferably delivering the glass in a stream and having `a plug 3controlled by handwheel 4, to regulate the si-ze and volume of thestream.

A plurality ofl gathering implements, which may be either solid puntiesor blowpipes, are so mounted and moved that their -jected to furthermanipulation, o r be remechanical arrangeouter ends intercept theflowing stream, re" main therein for a suitable period to gather theglass, and then move away to carry the gathers to positions where theymay be submoved for further treatment.

BFor this purpose the gathering implements 5 are supported in chucks 7rotatably mounted in an annular ridge 8 forming the periphery of acarrier 10, the latter being supported by a standard 11 andintermittently rotated by the hollow shaft 12 which carries a ratchetwheel 13 that is actuated by pawl 14. A pin 16 secures this pawl to arm15 and is engaged by the slotted end of a lever 17, pivoted to pillar18, and carrying roller 20, held by spring 21 against cam 22 on shaft 24supported in arm 25.

The cam 22 has one or more drops33, for advancing the carrier step bystep at suitable intervals. While the pawl 14 is making its returnstroke a spring pressed detent 34 engages recesses 35 in carrier 10,locking it against rotation.

A worm wheel 26, on shaft 24,is actuated by worm 27 on shaft 28 carriedin suitable bearings in base 31, the shaft being rotated in anyconvenient manner, either by connections with an associated machine, orby a variable speed motor 32 to permit the speed of the machine to bealtered according to requirements.

The gathering implements are preferably inclined slightly downward andare rotated upon their longitudinal axes to accumulate and evenlydistribute the glass upon the ends of the implements.

For this purpose each chuck 7 has a shaft 36, carried in bearings inridge 8 of the carrier 10, a bevel gear 37 being keyed to each shaft 36and driven by the outer set of teeth 38 on ring gear 39. The latter alsohas internal teeth 40 by which it is driven from idler 41, actuated bypinion 42 on shaft 43, revolubly carried within hollow shaft 12, idler41 being carried by a pin 44 in a bracket 45 on the carrier. Bevel gear46 on shaft 43 is driven by bevel gear 47 on shaft 28, to impart a.continuous rotation to the gathering irons. Owing to the relative rotarymovement of carrier 10 with shaft 12, and the similar movement of ringgear 39, with its teeth 38 engaging bevel gears 37, the continuousrotation of each gathering implement will be slightly retarded oraccelerated according 110 ues . 54 into one or more in positionIV, V, VIand to the periodslof movement or rest of carrier 10, but this does notaffect the function of the gathering implements and may be readilyminimized by Va proper timing .and ratio of the gearing.

Further treatment of the glass may be accomplished by presenting theimplements to a marverer 49 upon which the gathers will be rotated andmoved laterally, preliminarily shaping and chilling their outersurfaces. The marverer may be flat, or may have a curved working facgaccordingl to form of gather desired, and is supported in properrelation to the gathering implements by brackets 50 secured to standard11. In Fig. 1 the marverer is shown in its proper relation to thefurnace, and in Fig. 2 it is shown diagrammatically at the left of thefigure to illustrate its cooperation with the implements.

In Fig. 3 the translatory movements of the implements immediatelypreceding, during and -after gathering are shown diagrammatically. Theimplement just entering the gathering chamber is moved laterally intocontact with the downwardly flowing stream. rlhe lateral movement isarrested in that position, but since the gathering implement iscontinuously rotated the glass forming the lower portion of the streamis wound around or gathered upon the implement as shown in position l.Having obtained the proper size gather, the implement is moved laterallyto position H, carrying with it the lower end of the stream,

which then sags d into contactV with the next implement to which itadheres and is wound thereon. The winding action separates the cord ofglass connecting the implements, and the resultant stub ends, not beingchilled by contact with metallic severing devices, are wound upon andabsorbed into their respective gathers. When each implement reachesposition III, or another subsequent position of rest in its translatorymovement, it may be withdrawn from its chuck, in which it is removablyheld by the pin 51 pressed by the spring sockets 53 in thecircumferential groove 52, whereupon the implement with its gather maybe presented to other mechanism for further treatment.

Vhere marvering is desired the gathering implements are not removed atposition IH but continue their translatory and rotating motion until thegathers contact with the marverer for a suitable period, as shown VII,the removal occurring at a position indicated at or thereafter. Emptygathering implements may be inserted at any convenient position in thecycle before the chucks reach chamber 55. The grooves 52 in theimplements enable them to be reinserted at any rotary position of thechucks, and at once retained by the pin 51 entering the groove 52.

I ing the stream upon This will ordinarily be sufficient to rotate theimplement with the chuck.` If the implement stops rotating as forexample when it reaches the marvering plate,-the pin 51 will drop into asocket 53 and drive it positively.

Owing to the peculiar properties of molten glass, it may be desirable todeliver and gather the glass in a chamber the temperature of which maybe regulated to maintain the glass in proper working condition. 55designates such a chamber, which has a bottom orifice 56 in line withand somewhat larger than orifice 2, to permit the glass to flow throughit when the apparatus is out of operation, the chamber being heated byburners 57 of any well known kind provided with control valves 58. Anannular shield 59 may be mounted on the carrier to protect the mechanismfrom the heat of the gathering chamber.

By thus utilizing a iiowing stream of glass, or glass delivering means,the operation of which may be tion with a gathering mechanism that maybe caused to travel faster or slower, the size and volume of the gathersobtained can be accurately determined and varied. Furthermore, by thisprocessand apparatus successive gathers of uniform size and plasticityare obtained, which may subsequently be formed into finished ware freefrom scars and chill marks.
